chapter 27.2 Flashcards
the removal of the earth’s crust through weathering
erosion
when gravity takes eroded materials from one place to another
sediment transport
when erosion agents drop material off in different places
deposition
the land area that gathers water for a major river
drainage basin
the movement of water parallel to the shoreline
longshore current
what is the difference between weathering and erosion
weathering is the breakdown of materials/ erosion is the removal of materials
True or false: as the slope of a river decreases the speed of the water decreases
true
what are small streams that flow into larger rivers
tributaries
the land area that gathers water for a major river is called
drainage basin
as water flows downhill under the influence of gravity, water erodes earth’s surface
channels
what shape are young rivers
v-shape
rivers that are wide with gentle slopes
mature rivers
when rivers flood and drop their sediment load what is it called
flood plains
what are fan shaped sediment deposits that form at the mouth of a river
delta
what are the two types of glaciers
valley
continental
where are the two glaciers located
valley-in high elevation/ mountainous regions
continental- large land ares in colder climates
what is a cirque
bowl shaped basin
what is a arete
form where 2 adjacent valley glaciers meet and erode a long sharp ridge line
what is a horn
sharpened peaks
what do tributary glaciers create
hanging valleys
what are tributary glaciers
small glaciers that feed into larger glaciers
what shape of valleys do glaciers create
u-shaped
which side of a sand dune does erosion occur
windward side
side side of a sand dune does deposition occur
leeward side
